  • Figure 1
    Pelvic tumour: morphology
     

    A well-defined lesion in the paravaginal and parametrial right area is observed (red arrows). This lesion is hyperintense and heterogeneous on T2WI, observing multiple hypointense strands within it (swirled...

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Localisation; Special Focus: Neoplasia;

    A finger-like projection of this lesion infiltrates the right puborectal muscle reaching the ischio-anal fossa. The presence of this projections invading neighbouring tissues and structures (yellow arrow) suggests a...

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: eLearning; Special Focus: Neoplasia;
     
     
  • Figure 2
    Pelvic tumour: Locoregional findings
     

    The tumour displaces the vagina towards the left side but without invading its wall (blue arrows). Note the swirled appearance of this lesion with multiple hypointense strands within it (green arrow).

     
    Area of Interest: Musculoskeletal system; Imaging Technique: MR; Procedure: eLearning; Special Focus: Neoplasia;

    A finger-like projection which infiltrates the right puborectal muscle reaching the ischio-anal fossa (yellow arrows).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    The lesion is clearly in contact with the internal obturator muscle (green arrow), without infiltrating it.

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;

    Contrast enhanced sequences

    After contrast injection, the lesion shows a progressive and heterogeneous enhancement.

A well-defined lesion in the paravaginal and parametrial right area is observed (red arrows). This lesion is hyperintense and heterogeneous on T2WI, observing multiple hypointense strands within it (swirled appearance).
 
A finger-like projection of this lesion infiltrates the right puborectal muscle reaching the ischio-anal fossa. The presence of this projections invading neighbouring tissues and structures (yellow arrow) suggests a locally aggressive behaviour of this lesion.
